To all whom. it may concern:

Be it known that I, ALDEN L. PU'rNaM, a citizen of the United States of America,

' residing at Detroit, in the county of \Vayne and State of Michigan, have invented certain new and useful Improvements in Metallic Vehicle-lvheels, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to vehicle wheels 01" that type in which the rim is of channel section, and it is the object of the invention to provide means for attachment, thereto of a standard construction of demountable rim designed for attachment to wooden wheels. In the present state of the art one method of attaching demountable rims to wheels having Wooden follies is by wedge bearings which are adjtlsta'bly clamped to the folly by bolts extending transversely therethrougln- \Vith such construction the demountable rim is held from rotative adjustment by an anchoring bearing thereon engaging a cooperating bearing on the telly and which prevents the cutting off of the air valve and filler tube of the tire by creeping of the rim. Where a channel rim is substituted for the wooden felly other means must be provided ior securing and anchoring the demountable rim, and to this end 1 have devised the following construction.

In the drawings:

Figure l is an elevation of the wheel showing the demountable rim secured thereto; c

Fig. 2 is a cross section thercthrough, on line (is-00 of Fig. 1

Fig. 3 is a longitudinal section;

Fig. i is a plan view of a portion of the permanent rim with the demountable rim detached, showing an arrangement in which the anchoring bearing on the rim is adjacent to the air valve tube;

. Figs. 5 and (3 are respectively a plan and longitudinal section showing an anchoring construction not associated with the air valve tube; and

Fig. T is a scctionshowing the .manner of detachably engaging the wedge clamping bolt.

A is a metallic wheel which as shown is formed of complementary sheet-metal sections having the hub B. spokes C and rim I) integral. The rim is formed of a channel section, one flange E thereof being adapted to forma retaining bearing for astandard construction of demountable rim, such as F, and the opposite flange G forming a bearing for the wedge member -I-l which clamps and secures said rim F. i

The bolt J. engages an apertured embossed portion I on the channel rim extending through the channel and projecting through an opposite apertured embossed portion 1 for engagement with the wedge H and clamping nut J. With-wooden fellics the bolt is held from turning by longitudinal ribs thereon which press into the wood. Such a construction is not suitable for use with metallic rims, but it is essential to normally hold the bolt from turning and at the same time to permit of detachment when necessary. This I accomplish by engaging the threaded portion of the bolt with a correspomlingly threaded aperture K in the embossed portion 1 and providing the head L of the bolt with a bendable flange L. When the bolt is engaged with the bearing the flange L may be bent down so as to interlock with the flange E of the.

rim and prevent turning of the same, but whenever it is necessary to remove the bolt, by placing a wrench or other turning tool thereon it may be unscrewed, thereby bending back the flange L.

To anchor the dcmounl able rim from creeping one of the bolts J has sleeved thereon an anchoring member for engaging the colipc'rating anchoring shoulder on the rim. \Vith certain constructions of de- .niounlablc rims this anchoring shoulder is adjacent to the aperture oil the valve tube oi the tire, and for such constructions l employ the structure shown in Figs. 2 to 4-. This comprises an insert M placed in the channel of the wheel rim. which is apertured at M for the passage of the valve tubc. said aperture being in alinement with an aperture in the rim. The insert M is sccurcd by a bolt or rivet N engaging the embossed portion 1. and has a projecting threaded stud passing through the opposite embossed portion l for engaging the wedge ll and nut J. The member M is also n'ovidcd with a recess M for receiving the locking lug l on the dcmountable rim and thereby holding said rim from creeping.

With the construction shown in Figs. 5

and 6, the anchoring member Q; is not associated with the valve tube but is sleeved upon one of the bolts J and is provided with looking shoulders Q for engaging the cooperating locking shoulders on. the demountable rim.

l/Vith the construction as described, any

of the standard constructions of demountable rim applicable to wooden wheels is equally applicable to the metallic wheel, it

to permit turning of the wedge bearings out of the path of the demountable rim, and after the latter is in place re-turning said bearings and tightening the nuts. As, the point of bearing of the wedge is intermedia-te spokes the resiliency of the channeled rim Will cushion the shocks in a similar manner to the action of a Wooden wheel. What I claim as my invention is:- 1. In a Wheel, the combination with a channeled rim having an embossed portion therein, of a member in the recess formed by said embossed portion forming an anchor for a demountable rim, a clamping device for said demountable rim. and a connnon $0 bolt for securing said clamping device and anchor.

2. In a wheel. the combination with integral pressed sheet-metal spoke and chain nelrim sections, of a demountahlc rim for engaging said channel rimya clamping device for said'demountable rim. an anchor within the channel of the rim apertured for the passage of the air valvetube of the tire.

and having a locking engagement with said v 40 demountable rim, and a connnon bolt for securing said clamping device and anchor.

'3. In a Wheel, the combination with a channeled rim hav ng an embossed portion I therein, of a member in the recess formed at by said embossed portion forming an anchor for a demountable rim, and means for securing said anchor to said channeled run.

t. In a wheel, the combination with for a demountable rim, a clamping device for said demountable rim, and a common means en aging said anchor and clamping device with the channeled rim.

5. in a wheel, the combination with a channeled rim. of a demountable rim for detachably engaging the same, a member rigidly mounted in the channel of the rim, apertured for the valve stem. projections from said member at each side of said apen ture and a member projecting from the dcmountable rim engaged between said projections. I i

6. In a wheel, the combination with a channeled rim, of a demountahle rim for detachably engaging the same. said channeled rim having an embossed portion. an anchorage member having flanges engaging said embossed portion and formed with an aperture for the valve stem projections from said member at each side of said aperture, and an annular flange projecting from the demountable rim and circling an aperture therein for the valve stem and engaging between said projections.

7. In a wheel, the combination with a' channeled rim, of a demountable rim {or detachably engaging the same, an anchorage member within the channeled rim formed with circ'umterentially spaced outstanding projections, a clamping belt for said don'iountable rim engaging and securing said anchorage member, and a coactinganchorage member secured to the demount-able rim and engageable between said outstanding projections.

In testin'ion v whereof I atiiX my signature.
